There is an E next to an item trying to be purchase and can I delete preorder items
Help trying to figure out what does it mean when there is an E next to an item that tried to be purchased and can I delete these items
iPhone 4, iOS 7
The red 'E' means that it contains explicit content - you can prevent/allow buying explicit songs via Settings > General > Restrictions > Music & Podcasts > Explicit 'on' (allow) and 'off' (prevent).
It think that you can only view / manage / cancel pre-orders via your computer's iTunes : http://support.apple.com/kb/HT5714
